My grandfather Karl Bier was a first-class maker and architect. He died when I was very young, so I never knew him, but I have some of his furniture in my house, and his level of craftsmanship has always inspired me.

He made a burr puzzle out of hardwood that we still have. It has a shine and finish that comes from many, many hours of being handled in the 60 or so years since it was made.

I've modeled an exact replica of that puzzle, and I hope people have as much fun with this one as I did over the years with my grandfather's wooden one.

Set of planetary gears and arms to hold the planet gears in place.

Based off OpenSCAD code from thing:7390 (after cutting out significant portions of it - because the original thing is much more than a toy).

The gear ratios are very interesting, and (at least at first) non-intuitive, depending on the part that is held stationary.

With a fixed Annulus or Sun, this gives 1:6.
With a fixed Planet carrier, this gives 1:5.

This is a replacement oil barrel for the board game "Power Grid" by Friedmann Friese and Rio Grande Games.
This is the piece that I dislike the most in the base game. It's a brown wooden cube. So I wanted to create a piece that more closely reflects the game's art for the coal resource, namely a large pyramidal pile.
I am not quite satisfied with the look of this piece on account of how it looks more like a pile of cannon balls than anything else.

This is an implementation of Nikola Tesla's "Valvular Conduit" that acts as a one-way-valve without any moving parts.

This implementation follows Tesla's patent diagrams, perhaps too closely. It works, but the cap is a bit leaky so I plan to re-design it in the future.

My girlfriend challenged me to make a hand soap dispenser that is cooler than anything we could buy at Crate & Barrel (or similar stores). The result, after a number of design iterations, is this bottle which now inhabits our bathroom.

This dispenser is designed to reduce waste in a number of ways. First, it is easily refillable, and so can be used for many years. Second, as the pump is turned, liquid soap spills from the spout back into a hole in the bottle, thus recycling any drips. Third, this design makes it easy to get as much or as little soap as you want, while commercial soap pumps often dispense more soap than necessary with a single squeeze.

I was inspired to create this design by a pair of earrings I saw in a store. I liked the design and wanted to incorporate it into my next project, a necklace and earring set. I printed out a few of the diamond-shaped links and tried several arrangements, but ended up liking the fan-shaped design best. Paired with turquoise nuggets and silver accents, the jewelry has a Southwestern vibe. I finished it off with an "AP" label (my initials). I created the design in Illustrator and printed it using a laser engraver.

All the big 3D Printer suppliers always show off braingears printed as single items. This is to show that even our humble hobby printers are capable of printing a brain gear - all be it in seperate parts for assembly later.

This is the box version of the awesomely printable Companion Cube by Landru. You can put stuff in it. I tried to keep the box as easily printable as the original was.

I included the OpenSCAD script to generate it, it has few parameters that can be tweaked.

New in this version:
- slightly modified the lid and got rid of the very thin parts at the top of the box. If you want old variant, then there is a parameter for that in the openscad.
- all wall/lid/bottom thicknesses are separate parameters, easy to modify to the taste
- increased the default tolerance slightly, so the lid would fit more likely without much sanding
(haven't printed yet this version, but will shortly)

Print twelve of these and fold them together to make a modular ornament, desk toy, whatever. Uses the Snijlab living hinge design.

These are the plans for my wooden construction set, consisting of rods of various lengths with screw holes and a set of brackets. The brackets use T-slots to hold a captive screw/nut so all the parts can be laser cut.

This is a simple modification to the great ball bearing from pp3dp.
I colored it metalic orange, I will add pictures if I get arround to make them :-)

Another CSIRL (computer science without computer) project of NancyBidouille, the lasercut meeples+house are just a test but already usable :)

I first tried to model metaballs in OpenScad. That effort was preliminary, indicating to me that it's not an easy egg to crack.

This thing cracks the proverbial metaball egg.

I have implemented a metaball routine in Banate CAD which gives you fairly decent results in relative real-time. That is, you can setup a fairly simple network of 'balls', and generate an isosurface for them in a matter of about a second, or a few seconds if you want to go for much higher resolution, or have a network with a ton of balls in it.

Metaballs/Blobs are used quite a lot in games for getting that nice blobbly affect on characters. It tends to make things look more organic than what you can typically achieve with more mechanical mechanisms.

This is great for modeling as you can quickly try out various configurations of balls to get all sorts of blobby effects. The "seat", or "face" model included here consists of just 4 influencing balls, so it's fairly simple.

In the picture, I've used fairly high resolution. The model is much lower resolution, but realistically, it would print about the same.

Also, in the picture, I'm showing the influencing balls, just for visualilzation. I turn them off to actually generate the .stl file.

I think the approach I'm taking is actually unique, as I haven't quite seen it done my particular way in the literature. Not a bad result for NOT using the GPU, and doing it purely in Lua.

You can play with the .fab, but it won't have the same results as I'm getting until this Sundays (12/4/2011) release of Banate CAD.

This hanger was requested by a friend who is very environmentally conscious. I thought this was a great way to recycle 2 bottles while utilizing the TOM's capabilities! A design similar to this by Chinese designer Xuan Yu inspired this thing's creation.

One thing to note is that the holes to accept the threads to the bottles are not threaded. A compression fit seems to work well enough.

This thing is part of a final project for CPSC 183 Technology and the Law with Prof. Brad Rosen at Yale University. The idea of this project is to ask friends for ideas for physical objects that they would like to have that could be printed on the Makerbot TOM. I have designed them, printed them out and given them to the people who requested them. I also have uploaded them here to Thingiverse to add to the library of physical objects that people find cool, useful, or just plain fun!

Video of the Stead i Cam in action: youtube.com/watch?feature=player_embedded&v=PDLClM5rk5o

The Stead i Cam is designed by Frits Stam en Koen de Greef

features of the Stead i Cam:
+ removable / adjustable camera plate
+ design incorporates a feet for easy storage
+ weight swivels to compensate for an unbalanced camera
+ air bubble for leveling the camera
+ adjustable handle position with a screw thread which allows for very fine adjustments of the center of mass
+ light weight design

This project originated from the urge to create tools that help designers create professional results in times of budget cuts. With ‘Tools for Design’ we aim to create a community that helps in the development of instruments used in the design process. The Stead-I-Cam is an example of one of these tools. It supports smooth and professional moving video footage. It is created from a single sheet of laser-cut material, making it easy for any student to create and assemble. This open-source project cuts costs for such a professional tool and makes it accessible for every student / diy'er.

We love to see your own Stead i Cam so upload a picture of it!

This is a holder for Stargate coasters (holds 4)

A small (24x24mm) altar made for the Dungeons and Dragons campaign I'm currently doing with friends. It's made to hold an orb, which can be a marble. I didn't have a marble, so it hold a D20 in my case.

There’s nothing like housing your modern technology in the façade of old technology. This is a small laser cut box that can hold up to 8 full-sized SD flash cards. There is a small living spring that will hold the lid shut when it’s bouncing around in your bag. You can open the box from either side.

With Christmas coming up, this would make great easy to make gift. I know I’ll be making a set of them.

This holder is the second generation of a SD card box, the original version was not nearly as much fun.

This is a "car" created with a 3-d printer in order to fullfil the objective of a prechallenge of my university group "UC3M Challenge - Mission: MARS".
The prechallenge consist in making a "car" with the 3-d printer that is going to race in a 5 degree inclination ramp which is made of sandpaper.

For quite a while I have been trying to find a way to answer that question, What makes me, Me? I came to the realization that this was the final answer. I am a geek, through and through, and this coin explains that. The Face of it is a decent melding of Star Trek, Star Wars and Stargate, the Back has the simple and elegant word GEEK emblazoned on it. It screams that I am a Sci-Fi Bi Geek. ;c) And to top it all off it's printed on a 3d printer. What could be geekier.
